Can I make this forum sort the "normal" way?

There are web-forum programs which make it easier to keep track of whats new, what you have already read and replied to, and in my opinion look nicer. But I dont know if they cost money and Im sure they have a higher overhead in machine CPU so Im not sure I could recommend them for here. Especially if we lose access to all the previous conversations.

I know that the forum software used at stardestroyer.net is free of charge, but I don't know what kind of server requirements it has.
